Seems like a sort of light service mesh, but delivered from within the app, and very straightforward. I'll have to look at mDNS, had heard of it, but never read into it.

mDNS has been around forever (2002/macOS 10.2) but probably best known in the Apple ecosystem as Bonjour [1,2]. Much of Apple's big software and hardware products integrate it in some way.

Sure. The last Apple product I owned was an Apple II, so Bonjour is similarly something I've heard in passing, but never looked closer at.

I agree with your sentiment—seems like a kinda light weight fully integrated service mesh.
